MQTT-Bench : MQTT Benchmark Tool

This is the benchmark tool for MQTT Broker implemented by golang. This can benchmark the throughput for publishing and subscribing.

Supported benchmark pattern is:

• Parallel publish from clients
• Parallel subscribe from clients

Getting started

Installed

Publish

• Precondition
• The MQTT Broker is started.

$ mqtt-bench -broker=tcp://192.168.1.100:1883 -action=pub
2015-04-04 12:47:38.690896 +0900 JST Start benchmark
2015-04-04 12:47:38.765896 +0900 JST End benchmark

Result : broker=tcp://192.168.1.100:1883, clients=10, totalCount=1000, duration=72ms, throughput=13888.89messages/sec

Subscribe

• Precondition
• The MQTT Broker is started.
• The MQTT broker will keep the messages. It will be published the message with retained.

(Keep the messages before subscribing)
$ mqtt-bench -broker=tcp://192.168.1.100:1883 -action=pub -retain=true

$ mqtt-bench -broker=tcp://{host}:{port} -action=sub
2015-04-04 12:50:27.188396 +0900 JST Start benchmark
2015-04-04 12:50:27.477896 +0900 JST End benchmark

Result : broker=tcp://192.168.1.100:1883, clients=10, totalCount=1000, duration=287ms, throughput=3484.32messages/sec
